Game design

He should go with the computer science and do computer language training parallel to his UG education.

You can go for any humanities stream course, as science students have the advantage to go for any course.
But it's better that you opt for that course which you have studied a little bit in 12th.
So you may go for BCA/B.Tech but in my opinion, opt for any computer tech programming related course as it has a good scope in future.

Game design is basically a part of programming which you will study better in CS or IT branch, but if you want to go ahead in game designing, you can look for online courses about programming languages.
